Good evening all. I'm new to this computer thing with tuning and am pretty confused at this point. I'm following a checklist that tells me to kill the MAF, deceleration, COT, and EGR. I have a 1986 10 with a 5.3 from a 2001 Tahoe in it. I welded my own exhaust and put a 72mm turbo on it and I upgraded to larger injectors. Ford part number M-9593-g302. They are 47 lb/hr injectors. I also have a 2.5 BAR MAP sensor part number 12614973 from a Cobalt. Everything else is stock. I do have a wideband sensor, independent of the scanner, wired up and working correctly. I have what seems like a myriad of issues but I will ask what I think is the root issue. When I switched to the 2BAR OS I followed the steps on switching the VE table information and updating injector data as well MAP calibration. I went to start and it would either dump fuel and choke or it wouldn't start at all. I tried giving it more airflow through the idle tables. That didn't work. I finally got it to idle somewhat decently, but still rich and it hunts really bad, by reducing the VE table by half. What I thought was also weird is that it is reading somewhere between 13.5 to 15 on the wideband. So the fueling is somewhat close. I am new to tuning with computers but it doesn't feel right having to half the VE table. Thank you for your time and any help is greatly appreciated.
